Learning outcomes of the course unit

Student will study basic issues of physical geodesy, geopotential models and satellite methods for their creation.

Prerequisites

Fundamental principles of geophysics, astronomy and gravitational theory at the level of bachelor´s and master´s degree.

Co-requisites

The student should have advanced knowledge of physics and mathematics.

Planned learning activities and teaching methods

The lectures will be regularly included in addition to the lectures and follow-up exercises, there are also news from the subject, news and development perspectives.The same in the exercises with an emphasis on practical applications.

Assesment methods and criteria linked to learning outcomes

Verification of knowledge and skills takes place in exercises. Students are motivated to continuous study even during the lessons. The teacher repeatedly emphasizes essential profile information. The exam is carried out in the form of a test as well as in writing. Evaluation is carried out according to valid principles with a set scale of evaluation.
